Lean – En utveckling från produktion till välfärd och service : En litteraturstudie av hur Lean utvecklats från produktion till välfärds- och servicebranschen

Sammanfattning: This study consists of two studies around Lean. The studies are limited to two databases and three different sectors, the industry sector where Lean originated from, and the welfare and service sectors. The first study is a quantitative pilot study on published articles. The purpose was to get an understanding of what extent the different sectors get published, compared to each other. The result was illustrated in a graph where 40 articles per year were proportionally divided between the three sectors. The main study is a literature review where a scoring matrix was used to cull the selected articles. The remaining articles where compared to the “Toyota house” to answer the research questions: In what way has the definition of Lean changed from the manufacturing-based improvement philosophy it originated as, to the concept that is used in different sectors today? How does the specific sector affect the implementation of Lean, is there a difference in the Lean that is described in the literature compared to the Lean that is used in the welfare or service sectors? The study found in the chosen literature is that the sectors that are new at using Lean are using less of the tools available and in a smaller part of the organization, instead of using it on the whole organization. Many case studies where found that describes what tool was used, but not how they were used. One sector with many published articles was the construction sector, but they were overlooked due to the limitations of the study.
